Patients with macular edema usually do not undergo cataract surgery immediately. After the edema has subsided, the decision to operate can be made after evaluation based on the patient’s eye condition. Most of the macular edema is caused by inflammatory reaction and fluid infiltration in the macular area, as some cataract patients may have ocular inflammatory reaction after surgery, resulting in macular edema. If the patient suffers from macular edema before surgery, cataract surgery may increase the risk of intraoperative surgery or worsen the edema symptoms after surgery, so it is not suitable to perform cataract surgery immediately. After the patient’s macular edema is relieved, the doctor can judge whether the surgery can be performed according to the condition. Patients with macular edema should pay attention to eye hygiene and avoid eye fatigue, which may aggravate the condition. It is recommended that patients with macular edema should consult the hospital in time to assess their condition and under the guidance of the doctor for treatment.
